Sounds similar to this thread, which we weren't able to solve due to the application requirements: Firefox does not print When printing a 2MB document with plain html. Are you also trying to print a long table?

Someone might have filed, to might need to file, a "bug" for this.

Yeah, it sounds very similar. My document is made up of several smaller tables - it's difficult to describe but basically it's one long webpage made of HTML documents generated and combined by the third party application creating the HTML.

The only difference is that this only appears to happen on Windows 7, on XP is fine.

I'll have a look through the bug reports

thanks

Does Firefox still crash in a new profile?

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Thanks I'll have a go. It's a bit of a pain because I'm trying to support other users in a business environment - I'm not on Win7 myself and can't replicate the problem on XP, so I'm slightly reluctant to start creating new profiles, few things annoy my users faster than losing data.

I'll give it a go though. Oh if only we had standardised corporate builds....
